Apple Computer will begin selling a scaled down version of the high-end Nvidia 6800 Ultra DDL graphics card in order to better meet demand for the product, according to a MacNN report.

One of the Nividia 6800 GPUs are required to power Apple\'s new 2560x1600 pixel 30-inch HD Apple Cinema Display, which made its debut in July. But the graphics card company has been unable to produce stable versions of the 6800 Ultra card, delaying orders for Apple\'s 30-inch display by up to three months.

\"Both products feature 256MB of GDDR3 memory and 16-pipe superscalar architecture; however, the Nvidia 6800 GT features a slightly lower bandwidth of 32GB/sec for delivery of 525 million verticies and 5.6 billion textured pixels per second. The Ultra version features 35.2GB/sec throughput for 600 million vertices and 6.4 billion textured pixels per second,\" the report says.

Like the 6800 Ultra, the 6800 GT will block the adjacent PCI slot, reducing the number of available PCI or PCI-X slots from three to two on the Power Mac G5.

A message to Apple customers says the NVIDIA GeForce 6800 GT DDL graphics card will be available for order in early November. The company had previously informed customers that it hoped to ship orders for the 6800 Ultra and 30-inch display \"on or before October 25th\" (today).
